WELT-IN SOLE FOR SHOES.'

Specification of Letters Patent.

Application ined January 27, 1916. sriai'No. 74,626'.

To all 'whom #may concern Be it known that I, WILLIAM E. CLAYTON, a citizen of the United States, Y residingl at Portsmouth, in county of Scioto and State of stance and texture, it can be split and an abutment made, and thus do away with the so-called gem operation, but if not, then it is necessary to fasten something to the material to serve in the place of the abutment.

One of my objects is to provide an insole which affords enough substance and texture to admit of splitting the same in order to provide the required abutment.

A further object of my invention is to produce a very iieXible insole that can be manufactured cheaply and in a practical wa AT still further object of my present invention is to provide an insole which will practically preclude the penetration of moisture from the foot; and also to provide one which will admit of repair work being done after the first sole is worn through; in short it is my purpose to afford as good a sub stance as would an entire leather insole for repairing, if for no other purposes.

lVith the foregoing objects in view, my present invention comprises an all canvas welt insole.

In the accompanying drawings Figure l is a'plan view of the under side of the insole;

Fig. 2 is a longitudinal section thereof; and

Fig. 3 is a. transverse sectional view of the insole.

A, represents the uppermost layer of the insole. This is coated on the lower surface with an adhesive substance l, which, when heated, will cause the canvas duck layer A to adhere to the layer B, which is of relatively thick canvas.

After these two layers are thus pasted t'ocomposed of a thick layer of gether, the lowerI edges of the' canvas B are channeled as at'2, this channelingexten'ding. only part way, sayxone-half, through the canvas vlayer B. After being thus channeled, the channel 'is turned up, as shown in Fig. 3. Then thus turned up, a layer of canvas duck C is cemented to the under surface of the canvas B and made to surround the channel.

In this manner, an all canvas welt insole is provided which isvery light and flexible, and comprises as set forth two outer layers of canvas duck pasted to an intermediate layer of thick canvas, the edges of which, save the heel are channeled, thereby inclosing the channeling and forming a soft fleXible insole withan abutment made from two of the layers. l K Y The intermediate part of this abutment is an integral portion of the intermediate layer, so that in stitching through the welt 4, upper 5, and the abutment, the stitches eX- tend through a substantial and solid abutment of at least three layers ,of canvas, one of which is part and parcel of the intermediate layer of the insole.

I am aware that cushion inner soles for shoes have been patented, which have been felt, but felt lacks strength and texture to hold the sewing or inseaming of the upper and the welt to the same, and consequently required reinforcing of calf-skin or other soft leather on the upper side of the sole, together with heel reinforcing, because the felt did not have suiiicient strength to holdL theheel-nails. Asbestos has been used also in this general type of insole to keep the cold and dampness from the foot, but my present' invention differs from these because it is an all-canvas welt insole possessing enough substance and texture to admit of splitting at the edge to form the abutment. Vhen thus constructed, I do not have to reinforce the heel with the leather to provide suiicient substance as a fastening for the heel, nor dol I require sheep-skin as a lining vfor the upper side to give it a smooth surface for the foot.

Thus I am able toproduce a much less eX- pensive insole, which at the same time is as flexible as any other, and possesses the required strength and body.

I claim:

l. A welt insole comprising a compara-y strong pianotively thick layer of canvas having a p0rtion of its edges channeled to form a flap, said Hap being bent away from the edge.

2. An all-canvas Welt insole composed of three layers only, the intermediate layer being relatively thick and having a portion of its edges channeled, to form a flap, said flap being bent away from the edge, and one layer of the canvas made to adhere to and 10 inclose the iap thus formed on both sides.

3. A Welt insole comprising three layers,

Copies of this patent may be obtained for the intermediate layer being of relatively thick canvas, and having a portion oi its edges channeled, to form a flap, said flap being` bent away from the edge, a thin layer of material cemented thereto and forming a. cover, and a layer of canvas made to adhere to and inclose the flap on both of its sides.

In testimony whereof I aiix my signature.

WILLIAM E. CLAYTON.
